Dayton Superior Keeps Light Rail Expansion on Track

Recognizing the need to open up the City of
Calgary’s downtown core to residents of surrounding
communities, city leaders approved
an expansion to the West light rail transit
system (LRT). The expansion, to serve areas
west of the city between the Bow River and
Glenmore Reservoir, includes the first new LRT
line in 20 years. This new line includes elelvated
track in several locations and a tunnel
track under the Westbrook Mall parking lot.
The final station for the line will be just west
of 69th Street S.W.

The West LRT expansion covers an area
that, over the next 20 years will experience
a nearly 25% growth in population, going
from approximately 90,000 people to
120,000 people.

One of the project’s challenges was that the
contractor needed a coil tie that offered the
same tensile strength as the coil rod being
used on the project. In addition, the contractor
needed a resource able to provide track
inserts on an extremely tight delivery schedule.

After a competitive bidding process and numerous
jobsite visits, Dayton Superior was
selected by the contractor to manufacture coil
ties in ¾" and 1" along with coil rod. Thanks
to Dayton Superior’s capacity to manufacture and deliver products in a narrow time frame,
the company was also selected to provide
track inserts to the jobsite, meeting the demanding
project schedule. The company
provided further product solution support to
the project with our Segmental Bridge Epoxy.
The epoxy’s ease of use reduced the amount
of time needed by labor for product application.
Dayton Superior also provided Bar-Lock
couplers for use in the precast arc detailing in
the new stations and bridge overhang brackets
and hangers used on the Sarcee Interchange;
where the design on the overhang was crucial
due to the limitations on the NU style girders.

“Dayton Superiors products, customer care,
and knowledgeable staff far exceed any other
in the industry. It has been great working
with Dayton, and I look forward to doing it
in the future,” said Kimberly Evanoff, Buyer
with SNC-Lavalin Constructors Inc./Graham
Infrastructure LP, A Joint Venture.
